Vertical field effect transistor with sub-15nm gate-all-around on Si nanowire array

Abstract

A vertical MOS architecture implemented on Si nanowire (NW) array with a scaled Gate-All-Around (14nm) and symmetrical diffusive S/D contacts is presented with noteworthy demonstrations both in processing (layer engineering at nanoscale), in electrical properties (high electrostatic control, low defect level, multi-Vt platform) in the fabrication of CMOS inverters and in the perspective of ultimate scaling.
